Value Collection 5072BMG Hex Head Bolt 1/2-13 Grade 2

Product Description

The VALUE COLLECTION 5072BMG is a Grade 2 steel hex head bolt with a 1/2-13 UNC thread and a 4-1/2 inch length under head. It features a hot-dipped galvanized finish that provides corrosion resistance in outdoor, wet, or treated-lumber environments. The bolt is partially threaded with a 3/4 inch hex drive and meets ANSI/ASME B18.2.1 dimensional standards. This fastener is suited for general structural and mechanical assembly work performed by contractors, millwrights, ironworkers, and maintenance technicians across commercial and industrial applications.

This bolt is commonly used in light structural framing, equipment mounting, and general-purpose fastening where a galvanized finish is required for corrosion resistance. The partial threading provides a stronger shank grip in thick material applications, making it appropriate for wood-to-steel connections, deck framing, utility structures, and general construction assemblies. It is sold in multiples of 25 units per order.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard nuts and tapped holes
• Hot-dipped galvanized finish for superior corrosion resistance compared to electroplated alternatives
• Partially threaded shank provides additional grip strength through thick material
• Grade 2 steel meets ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 standards
• 3/4 inch hex size compatible with standard wrenches and impact drivers

Compatibility

Designed as a standard inch-series hex head bolt for use with 1/2-13 UNC nuts and tapped connections in general structural and mechanical assemblies per ANSI/ASME B18.2.1 specifications.

Installation Notes

Installation is performed with a 3/4 inch wrench or impact driver rated for the fastener size. Always use a properly sized flat washer and nut to distribute clamping load, particularly in wood or soft material applications. Follow applicable building codes and structural specifications for torque and fastener spacing requirements. Inspect the galvanized coating for damage before installation, as compromised coating reduces corrosion resistance.
